Hello,
How to set up canvas so whatever cannot fit at a border will come up at the opposite border?

I was wandering how to set up canvas so whatever cannot fit at a border will come up at the opposite border? So for example if i use some flower brush near the top of the canvas and it will go over the top of the top canvas border the part of the brush that didn`t fit would automatically come up at the botom border. I need this for 360 tubular printing , so imagine my 50x50 canvas is actually not a square but in fact a tubular shape, so top and botom are connected. This way i can be sure that the two brushed parts matches perfectly.

Thanks
John

Hi @Johngog
OK, here is another approach. In this approach that the top edge of the document and bottom edge of the document when rolled up will show a continuous pattern.

- Create a document that is an even number of pixels (divisible by 2).
- Create a pattern that fills up the document yet don't go near the top and bottom edges yet. I used butterflies as my example and the document size is 1000 x 1000 pixles

- Now use the command Filter > Other > Offset with the following settings (change yours for vertical offset to be 1/2 your pixel height

- The image you now see has the borders in the middle with some white space as below

- Fill that whtie area in the middle with the pattern you want to cross the top and bottom boundary:

- and the apply the offset filter again with the same parameters to rotate the image vertically back to original:

- And you are done

Hope this helps some
